摘　　要：基于3S技术平台,将ASTER遥感数据与土地利用现状图和地形图相结合,采用决策分类方法对抚仙湖东大河小流域磷矿开采区植被类型进行分类研究.研究结果表明,基于3S的多源数据融合对小流域内不同植被类型信息具有较强的识别能力,通过野外随机抽样证实,抚仙湖东大河小流域磷矿开采区植被类型遥感解译准确率92%.The paper explores the combined use of ASTER remote sensing data and the current land-use map and topographic map based on the 3S technology in the study of the classification of vegetation in the working section of the phosphorite mine in the watershed of the Dongda River of the Fuxian Lake basin.The result shows that the combined use of multi-sources data based on 3S is effective in the identification of different vegetations in the area.And random field sampling indicates that the correct rate of remote sensing interpretation is 92%.
